UPD4482321 Overview
The µPD4482161, µPD4482181, µPD4482321 and µPD4482361 integrate unique synchronous peripheral circuitry, 2-bit burst counter and output buffer as well as SRAM core. All input registers are controlled by a positive edge of the single clock input (CLK). The µPD4482161, µPD4482181, µPD4482321 and µPD4482361 are suitable for applications which require synchronous operation, high speed, low voltage, high density and wide...
